What word describes the following shape?
Airway
Airfoil
Aeron
Airflow
When a plane is in flight, what's the main difference between the air below and above its wings?
The air above the wings has lower pressure
The air below the wings has lower pressure
The air above the wings has a higher temperature
The air below the wings has a higher temperature
Streamlined objects experience less drag. Which of the following vehicles best fits the description "streamlined?"
Why don't jumbo jets have propellers?
Because their wings are aerodynamically shape
Because only helicopters have propellers
Because jet engines provide more thrust
Because they are powered be jet fueled, not friction
What can you infer about the airplane parts called "elevators?"
Manipulating them allows the plane to move up or down
Manipulating them allows the plane to turn left or right
Manipulating them allows the plane to go forward or backward
Manipulating them changes the forces of weight and drag
A parachute with a larger canopy will create:
more lift
gravity
more drag
The descent of a parachute can be slowed down by:
making the canopy bigger
making the vent bigger
making the load lighter
making it from metal
The pilot of a hot air balloon pulls a cord to open the parachute valve. This causes the balloon to:
Turn left
Ascend (go up)
Descend (go down)
Turn right
Adding a vent hole to the parachute canopy will:
Cause a crash
Make the parachute more stable
Make the parachute rise
A hot air balloon rises because:
It is filled with gas
Cold air is lighter than warm air so it rises
The molecules in warm air are farther apart making it less dense
The pressure inside is higher
All of these are parts of a hot air balloon, except:
Envelope
Parachute valve
Box spring
Basket
Burner
The blue control surfaces are the Ailerons. They control:
Wind speed
Yaw
Roll
Pitch
Where the pilot and controls are:
Cockpit
Fuselage
Envelope
Vertical stabilizer
The rudder causes the nose of the plane to turn left or right. This is called:
Pitch
Roll
Yaw
Drag
This part is responsible for an airplanes left and right stability. It is called a:
Horizontal stabilizer
Flaps
Diagonal Stabilizer
Vertical stabilizer
A spinning propeller creates thrust using Newton's Third Law which states:
Bernoulli copied me.
For every reaction, there is an equal action.
Apples taste good.
For every action, there is an equal and opposite reaction.
Most spacecraft and rockets have very small fins. Why?
You don't need to steer a rocket.
There is no air in space.
They cause too much lift.
I don't know, give me the answer.
If an airplane is cruising at constant speed and height, it must mean:
Thrust = Drag and Lift = Weight
Thrust is greater than Drag and Lift = Weight
What does a parachute do to an object falling towards the ground?
It slows it down.
It speeds it up.
Nothing.
Hit the nae nae.
What is the name of top part of the parachute that resists air?
resister
mushroom
canopy
pack
